I've had one of these for a little while and have been using mics that use a small Jack plug. I've just now bought some AT831B mics. If I connect them via their individual power supplies they work just fine but as I want to use them for stealth recordings I don't want to have to carry 2 power supplies and two one meter long cables.

Well I just tried again with the metal convertors and it's working fine. Very strange.

Do not connect mics straight to p48. You will destroy them.

If you want to use them with p48, you need phantom adapter. These mics are three wires. One wire is for power, second is for audio signal, third is ground. Phantom adapter steps down p48 to small voltage and divide this voltage between wires. This is the right way how to power these mics. The second purposed of phantom adapter is that it converts mic's unbalanced signal to balanced signal. Then you can use long cables between the adapter and the preamp.

It is possible to use this mic in two wire configuration with classical battery box (9 V) too. But the mic is not properly powered in this way and you get distorsion on high SPL. 4.7k mod is Chris Church's mod (you put the resistor 4.7k between pin 2, 3). This mod enable you to use the mics in two wire configuration with 9 V battery box for high SPL too.

I'm sorry but I don't understand all the terminolgy. What is p48? Are there any adaptors that you can recommend. Thanks

p48 mean phantom power 48V. Condenser mics are working with this voltage, and a lot of preamps/recorders provide this voltage. But AT831B is electret mic, it need around 9V. Here is example of phantom power adapter for electret AT mics. I do not know, if it is working with yours. It is better to ask in the forum which adapter is for AT831B. Or better look into the mic documentation.https://www.amazon.com/Audio-Technica-AT8538-Power-Module/dp/B000ZLX3EY

I already have two AT8531, they came with the mics but I want to try and avoid having to use them because of the extra weight to carry plus the two leads extra leads. I will take a look around and see what adaptors are available in Europe as I live in London.

Yes, i understand. I think the best way is go for Chris Church battery box and Y cable with 4.7k mod. Y cable should have 2 mini xlr inputs (for your mics) and output one mini stereo jack (for battery box). Then you will connect - Mics -> Y cable with 4.7 mod -> Battery box -> Ext in (Tascam). You can buy second Y cable without 4.7k mod for recording quiet acoustic shows, then you will use - Mics -> Y cable without 4.7 mod -> Battery box -> Ext in (tascam)

Because of the gear you've bought, you are now trying to fit a round peg into a square hole. Unfortunately, while the adapter you're asking for is available, in my opinion that wouldn't be a very good option. See the last paragraph for details.

First of all, I agree with the other responses that you should buy a two wire battery box.

Most stereo microphones that use 9V power, also known as Plug In Power (PIP), terminate in a single 3.5mm stereo connector. If your mics were terminated similarly, you could use the Ext In connector on your DR100mkIII to power your mics.

However, since you have two mono microphones, you cannot connect your mics to the DR100mkIII, so I agree with the others that a two wire battery box is your best answer. They are tiny.

You also need the 4.7k mod if you'll be recording loud music...without this mod your mics are going to distort at high volumes. This is a very simple mod.

OK, so if you insist on the phantom power adapters, this is what you need to buy...

I'm going to be honest though that this would be a poor decision compared to the battery box. Read the reviews of the DR100mkIII from users that operate the DR100mkIII with phantom power turned on. Phantom decreases battery run-time on the DR100mkIII significantly. In my opinion, you'd be solving one problem and giving yourself another.

Battery boxes are very small compared the size of the DR100mkIII.

Finally, it's unfortunate that you've probably purchased the DR100mkIII because you mistakenly thought that you needed a recorder with two XLR connectors in order to connect your mics, but since you're a stealth taper, I would consider selling the DR100mkIII and buying a handheld recorder...and again use the battery box solution recommended above.

Since you said you're trying to stealth record, if I was in your position I would sell the DR100mkIII and buy a smaller handheld recorder. And rather than using PIP from the recorder, buy yourself a 9V battery box to power your mics. They are tiny, inexpensive and fairly commonplace.

Church Audio sells several battery box designs that are popular on taperssection and are less than the size of a 9V battery.

The basic problem is that your recorder is incompatible with your microphones, so you're trying to fit a square peg into a round hole and there simply are very few options available for the adapter you're looking for. Mic's that are designed to be powered with a 9V power source just aren't compatible with a recorder that supplies 48V phantom. However, if you insist on keeping the DR100mkIII, the product that you need is available in the link below. As far as I know, Naiant is the only source of this type of adapter.

A third option which has not been suggested is to purchase a recorder that supplies 'plug in power' (PIP) directly to your mics from the 3.5mm mic in connector jack. However, the problem with this option is that most of these recorders underpower the mics...while the mics may work they usually don't get enough power to handle the high Sound Pressure Levels (SPL) at a loud live music concert, so underpowered mics will distort when the sound gets loud. Some people have reported good results using a few handheld recorders that apparently put a slightly higher voltage through their 'mic in' jack than other manufacturers. I would caution you to do plenty of research though...you should assume that a recorder with PIP will NOT provide enough power to your mics to record loud music concerts.

I do have a Sony PCM-M10 but what drew me to the Tascam was the fact that I can record at 24/192. I know that might sound a little extreme but....

I have used the Tascam with CA14s and the Church Battery box which I still have.

The Audix adapters don't provide any information except that they work with electret mics... I have a pair of something similar that work with my PIP mics, so they might work for your situation. I'd try this first. The Superlux product seems to be specifically designed for the Superlux mics. Without additional specs, not sure.
